Question CPU overheating

[lonewolf1601]

I've been having issues with my PC randomly turning itself off. After some investigation I've determined that the CPU is getting hot enough (115C) to force a shutdown. It had only happened once or twice while gaming in that past but happened every time I tried to do a full scan in windows security. However now it heats up to the point of shutdown within minutes.

I'm thinking that it's an issue with the AIO cooler that I got from ibuypower as it's started to make a buzzing noise. I've also noticed others have had issues with the cooler around the same time frame (2 years of use).

I'm going to switch it out to see if that's the issue but I'm not sure if I should go with another water cooler or if I should get an air cooler. Looking for some input on this matter and what would be a good replacement or additions to keep it cool.

Most aluminum 360mm radiators are pretty much the same. Go with a cheaper one you like the looks of.

If you want to look at premium 360mm AIO, look for the all copper ones.

Thermalright has some pretty amazing air coolers though. Not the best fans, but you can always swap them out.

What you describe sounds like failure of circulation of the liquid coolant in the AIO system, which can be caused by any of several issues. You can NOT repair any of those, so you are right to plan a replacement. These problems can happen to any AIO system, although the better ones take much longer to develop troubles. Thus I agree you should consider whether to switch to a good air-cool system. However, I don't have enough experience to advise whether that is practical for your particular set-up, so I hope others who DO have that knowledge can advise.
